We demonstrate the selective excitation of individual Raman Stokes lines of up to the ninth order by pumping with rectangular-shaped optical pulses at 530 nm from a frequency-doubled adaptively pulse shaped fiber master oscillator power amplifier. We achieve extinction ratios of up to 15 dB between selected and adjacent Raman orders in a 1-km-long fiber.
我们展示了通过从倍频自适应脉冲整形光纤主振荡器功率放大器中以 530nm 的矩形光脉冲进行泵浦,对高达第九阶的单个拉曼斯托克斯线进行选择性激发。在 1km 长的光纤中,我们实现了高达 15dB 的选定拉曼阶与相邻拉曼阶之间的消光比。
